What is a quasar in space?

Question

Layla Anderson · Accepted Answer

A quasar is an astronomical entity that emits a very high levels of electromagnetic radiation. A single quasar can give off more energy than 100 normal galaxies. It believed that what we are really seeing is the interaction of matter with massive black hole at the center of galaxy.

An intense source of electromagnetic radiation, a quasar can release more energy in a single photon than 100 normal galaxies. The term "quasar" may refer to quasi-stellar objects, or "quasars," but what exactly is a quasar and why does it emit such a bright light? When matter interacts with the supermassive black holes at the center of most known galaxies, it forms an accretion disk, and the gravitational pull of the black hole causes the matter to heat up to millions of degrees, releasing energy in the form of jets of radiation millions of light years away from the black hole. This is how a quasar is formed.

Levi Acosta · Answer

undefined Supermassive black holes at the centers of galaxies, which accrete large amounts of matter, are the source of quasars, which are highly energetic and distant celestial objects that emit exceptionally large amounts of energy, primarily in the form of electromagnetic radiation, including visible light, ultraviolet light, and X-rays. The friction and gravitational forces involved in this accretion process generate the intense radiation that quasars emit.
